Description MISHIMOTO MMTC-T1-19 Transmission Cooler, Silver for CHEVROLET Silverado 1500 / GMC Sierra 1500 2019-2025

The Mishimoto MMTC-T1-19 Performance Transmission Cooler is a direct fit cooling upgrade designed for compatible Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. It helps manage automatic transmission fluid temperatures during demanding driving conditions, including towing, hauling, off-road use, and daily operation.

The cooler features a durable 17-row tube-and-fin core with 266% greater core volume, 339% greater internal tube area, and 322% greater external fin area compared with the factory transmission cooler. Its enlarged cooling surface is designed to improve heat dissipation, while the tube-and-fin construction supports efficient fluid flow.

The assembly uses CNC-machined -6ORB adapters and factory-style quick-connect fittings for integration with the original transmission cooler lines. The supplied direct fit bracket and mounting hardware simplify installation. The cooler is supplied in a silver finish and is covered by the Mishimoto Lifetime Warranty.

Note: This product does not fit 2024 and newer Chevrolet Silverado 1500 or GMC Sierra 1500 models equipped with the 2.7L I4 L3B TurboMax engine and second-generation Hydra-Matic 8L80 transmission. For 2019 model-year trucks, verify the engine and transmission codes before purchasing. Compatibility must be confirmed for the specific vehicle configuration.
